What is the minimum square footage of heating surface at which you must have a license to operate the boiler?

In Ohio, the requirement for obtaining a license to operate a boiler is tied to the size of the heating surface. The minimum square footage established for this requirement is 360 square feet. This standard is crucial for ensuring that operators have the proper training and knowledge to manage the safe operation of larger boilers, which can present more complex challenges in terms of safety and efficiency.

Boilers with a heating surface below this threshold typically fall into categories that allow for operation without a license. These smaller boilers generally involve less risk and complexity, making licensing less critical. Thus, the threshold of 360 square feet serves as an important regulatory measure aimed at promoting safety and oversight in boiler operation within the state.
